Honorable Mention

Digital oscilloscopes generally require a PC, but they don’t always have a display built in. This digital oscilloscope has a nicely sized screen and can be a great addition to any workbench. The LM3S9B96-based design uses the extended peripheral interface bus and direct memory access to drive an LCD directly without a graphics controller. The internal RAM is used as the display buffer. The embedded RTOS simplifies the software required for the various tasks. The quadrature encoder interface is used for a scrolling knob.
